Specification of Letters Patent.

To all 0720mz't may concern Be it known'that I, STEPHEN E. Btmrn, a citizen of the United States. residing at Hamilton, in the county of Steuben and State of Indiana, have invented a new" and useful *indmill-Lubricator, of which the following is a specification.

The invention relates to improvements in wind-mill lubricators.

The object of the present invention is to,

improve the construction of windmill lubricators, and to provide a simple, eflicient and durable device of'inexpensive construction,

drawings, and pointed out in the claims hereto appended; it being understood that various changes in theforlmproportion,

' size and minor details of construction, within the-scope of the claims, may beresorted to without departing from the spirit or sacrificing any of the advantages of theinvention. -In the drawings :Figure lis a sideelevation of a lubricator, constructed in accordance'with this invention and shown applied to a Windmill.

-- In the accompanying drawings in which is illustrated the preferred embodiment of,

the invention, 1 designates a lubricant tank or reservoir, mounted upon and supported by a horizontal'bracket 2 and secured to the same by bolts 3, or other suitable fastening devices, which pierce the-bottom of the tank or reservoir and the supporting bracket. The supporting bracket. which may be of any preferred construct-ion. is provided at its inner side with. an L-shaped attaching .arm 4, havinga depending portion 5 fitted against and secured by bolts 6 to the upper port-ion of the rotary frameor turn table 7 v of a windmill. The tank or reservoir 1, which is preferably provided with a hinged cover 8', is equipped with a horizontal'series of approximately rectangular troughs 9. ex-

tending through the front wall of the'tank or reservoir at the upper portion thereof,

and projecting interiorly and exteriorly of the same. The troughs, which have common front-and rear walls, are separated by verti-- cal partitions 10. and they are closed at the r top exteriorly of the tank orreservoir by a horizontal top wall 11. The exterior projecting portions of the troughs are provided at their bottoms with depending nipples 12.,

which are connected with the upper ends of pipes or tubes 13, 14 and 15, adapted to conduct oil to the various bearings of the windmill. The device may be equippedwith any desired number of troughs and tubes or pipes to adapt it to the character or type of windmill to be lubricated. The pipes or tubes troughs to oil cups or passages 16 for lubricating the bearing 17 of the shaft 18 of the windmill. I

The tube or pipel4, which is short, ter minates above the pitman 19 of the -windmill, and it is adapted to deliver oil into two separate compartments 20 and 21 of a substantially elliptical or oblong pan or receptacle 22. The pan or receptacle 22', which 13 extend fromtheir respective is carried bythe pitman in the up and down movements thereof, has a central transverse partition 23, and is provided at the bottom of the compartment 20 with a short depending downwardly tapered pipe or nipple 24 to fit in'a'n upper oil cup or passage 25 of the pitman'to supply lubricant to the upper bearing 26 thereof. -;A relatively long pipe or tube 27 extends from the bottomof the other compartment 21 of the oil pan or receptacle to the oil cup- 28- of-the lower bearing 29. The oil pan or' receptacle is oscillated and is shiftedwithrespect to the pipe or tube '14; bylthegpitman pf the windmill, and on the lip-stroke the compartment 20 of the an or.'recepta'cle '22 is'ar-t ranged directly eneath' the pipegor tube 14,

while on the down-stroke, the other compartment 21 is located beneath the pipe or tube 14. By the particular construction and arrangement of the oil pan or receptacle, the upper and lower bearings of the pitman are supplied with clean oil, when a supply of oil is conveyed to the troughs by the means hereinafter described, which would not be the case were all the oil caused to pass through the upper bearing of the pitman, as the lower bearing would then be but poorly lubricated. with oil containing much of the dirt accumulated in the upper bearing. The pipe or tube 15, which is also relatively short, extends from its respective trough to the guide 30 in which slides the upper end of the pump rod.

Oil is conveyed to the inner portions of the troughs 12, which are open at the top, by means of a series of conveyer buckets 31 and 32, carried by an'oscillatory frame 33, composed of spaced parallel sides and a connecting portion 34 to which the buckets are rigidly secured. The sides of the frame 33 are arranged at the inner faces of the sides of thetank or reservoir, and they are fixed to a horizontal shaft 35, piercing the sides of the frame and the side walls of the tank or reservoir and extended beyond the same at one side thereof. The grooved pulley 36 is mounted on the outer extended portion of the horizontal shaft and receives a chain 37, or other flexible connection secured at one end to the periphery of the pulley 36 at the bottom of the groove and connected at its other end to a wire 38, passing through a central vertical tube 39 of the windmill and extending to the lower portion of the tower so as to be within easy reach fro-m the ground. The conveyer buckets are open at one end and closed at the other; the buckets 31 are preferably cylindrical, and the other bucket 32, which is of elliptical form, is designed to hold twice the quantity of oil as the buckets 31 for supplying the trough -to which the pipe 14 is connected, so that each of the bearings of the pitman will receive the same amount of oil as the other bearings of the windmill. The oscillatory frame is maintained at the limit of its downward movementby a coiled spring 40, disposed on the horizontal shaft and connected at one end to the same and having its other end 41 extended and secured to the adjacent end trough, but the end 41 may be secured to any other fixed portion of the device. When the pulley is rotated by the operating wire to rotate the shaft, the. spring is placed under uate path and are partially inverted, as

illustrated in dotted lines in Fig. 3 of thedrawings, to discharge their contents into the series of troughs from which the oil Hows through the pipes or tubes 13, 14 and l5 to the various bearings to be lubricated. As soon as the operating wire is released, the coiled spring swin s the oscillatory frame and the conveyer uckets downward from the position shown in dotted lines in Fig. 3 of the drawings to that shown in full lines in the said figure. Owing to the location of the inwardly projecting troughs and the arrai'zgeinent of the transverse pivot shaft at a point below and slightly in rear of the vertical plane of the inner wall of the troughs, the buckets swing through approximately one half of a revolution to carry them from the bottom of the trough to their discharging position. and they project over the troughs before the conveyer reaches an upright position, thereby insuring a proper supply of lubricant to the troughs. Oil Ina be supplied to the reservoir until the latter is filled up to about the plane of the horizontal shaft without danger of any leakage or loss of oil. The bearing at one end of the shaft is .covered by a cap 42, and a curved guard or housing 43 is secured to the opposite wall of the reservoir and extends around the upper half of the grooved pulley to protect the same.

What is claimed is 1. A lubricator of the class described comprising a reservoir having a closed top and provided with a trough spaced below the top and projecting from the inner face of one of the walls of the reservoir, a pipe extending from the trough for conveying the lubricant to the bearing to be lubricated, a horizontal shaft located below and slightly in rear of the vertical plane of the inner wall of the trough, a conveyer pivoted by the shaft and being of a size to extend from the shaft to a point above the trough, said conveyer including a rigidly mounted bucket arranged to swing upwardly through approximately one half of a revolution from the lower portion of the reservoir to a point above the trough and arranged in a position to discharge its contents into the trough when the conveyer is in an upright position.

9.. A lubricator of the class described comprising a reservoir having a closed top and provided with a trough spaced below the top and extending through one of the walls of the reservoir and projecting into the same from the inner face of such wall and having an outer portion arranged exteriorly of the reservoir, the outer portion being covered and the inner portion being open at the top, a pipe extending from the outer portion of the trough for conveying the lubricant to the bearing to be lubricated, a horizontal shaft located below and slightly in rear of 6- prising-a reservoir having a closed top and .1
